I just wanted to ask, what was the one thing you started doing (or mastered doing) that really helped you "step up" your multiboxing game? (It doesn't have to be good to great, I'd accept "mediocre" to "ok" as well ).
Comes down to a few different things like:

1) This site & the Community within.
2) Isboxer - With out a doubt!
3) Merc's 2 step macroes!!
4) Persistence, trial and error.
5) Again this site, the invaluable guides, info, helpful responses from others, helping each other etc!!
